nectionl with pumps, especiallyf those that are drivenl by electrically operated 'motors,'

and which operates to deliver the sterilizing liquid into the suction pipeof the-pump prior to the deliveryv of thexwater to the distributing mains.

More specically, the invention resides in the provision of automatically controlled valve mechanism whereby lafsterilizing solution may be diluted to av desired degree and `then fed int-'oV the "suction pipe of a water supply' pump.

In accomplishing these and other objects,` I have provided the improved details or"` construction, the preferredforms vo:t` which are illustrated in the accompanying drawcontaining tank and loatmechanism.

Figure 4; is a view showing diagrammatilcally the arrangement ofthe'device and its connections with'a water supply pump.

Referring more Vin detailyto the several'- views of the drawingsi 1 designates what may be a small storage tank or receptacle into whichA a liquid sterilizi'ng solution may be fed by gravity or other ressure from a-source of su l desivnated at l, vthrough a conduit 2. Theconduit.

communicates with the tank through an opening 3 in the base thereof at one end vand the 'opening is tapered to provide la valve seat4 1 from and against which-:thelower, taperedend 5 of a'valve stem 6' may be ad- Vjusted to control the flow of Vvthe liquid'into the tank. The valve steiniisslidably conmeans of ya `float 8 vthat is fixed at the end tained in a guide :frame 7 Y iixe'dywithinv the tank andv is automatically adjusted 'in ac':

cor'dancewith the rise'and fall of liquidfb'y ot a lever 9v pivotally supported by pini 1() within the 'guide frame. yThe shorter end of 4thelever has `.operative connection with the valvepin so that the vessel will normally be kept. about half full or more of liquid.

At the opposite end of. thetankis an out'- let 12 into which the nipple 131015 `the bonsing 111, of' a regulating valve, is threaded. The flow of liquidliirom thetank into the valve housing 14 is underfthe control of a v valve stem 17 having ataperedflower end l 15 adapted to a seat16 leading into the opening or outlet -12and flowirom the valve housinglthrough a base or discharge' opening 18 therein isv under the-control' of a manually'adjustable valve stem 19 extended i,

upwardly and-threaded.through a packed gland 2O and provided' at"v its end with .a-

wheel 21 wherebyit may berotated to adrate of discharge. I v

The upper end of the valvestem 17 is connected by means of aV short link 23 `with the ar1nature'211,ofl a solenoid 25. g The sole-` noid vcoilis electrically connectedv by wires 26'26"` --with the Vcircuit wiresl 27--2754 through which electrical energyis supplied to an v'electric vmotor M that operates the:

pump P, so thatwhen the 'motor circuit is closed, the solenoidwill be 'energized and the armature willbe lifted so asIto 4move 'the yvalve stem 17 upwardly toopen the Vport 12. A switch 59` is. interposed 'inthe circuit. connections as shown in Figure 1,

is moved downwardlyto close'the outlet`12.

" Th armature is supported by an arm 28 which' in turn is pivotally supported-from a vpin 29 'and a spring 30 is attached tothe arm.

to draw the armaturev away from the sole- Vnoid and positively close the valve when..

ythe circuit isr opened.

vLocated belowthe discharge opening. 1 8 of the regulating valve, to receive the liquid therefromis al second ltank 60 inwhich .the

sterilizi'ng solution is: diluted and whichis ofl practically the same construction as vthe vtank -1 'and has a fresh water inlet 31' at 'just the area of the dischargeopening and 'and when the switchcircuit is opened, the solenoidv is de-energizedand the milvestemV f one end under lthecontrol ofa'manually adjustable valve stem 32. 'A conduit 34 from a .source of reshwatersupply is connected to in accordancejwiththe adjustmentof stem` .the opening.V 31 to supply Water to the tank no' i Authie otherend ofthe isa baseV A outlet vvvithwhich a conduitf36 is attached` 1 andwhichleads to the suction pipe 61 of" the pump; the pump having a discharge pipe 62. rIhis outlet 35 has a tapered Valve seat 37 trom and vagainst which the tapered end f 38 of a valve stem 39 may be adjusted te control Vthe flow into the conduit 36. The

, valve stem is slidably supported in a guide Vframe 4L() and is under the control of a oat l1 vat the end of a lever`42 that `has operaV f tive connection With-theste'm and ispivot- :tally carried at its other endfby avpivot pin 7*,13 inthe guide trame' l-O.
